Housing & Infrastructure in Deville
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Deville's residential inventory spans multiple construction eras, with the median build year of 1995 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints — a plumbing practice banned that year — while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
Most homes in Deville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Deville Homeowners
Property equity in Deville runs well ahead of estimated remediation costs — a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Deville are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 2% below the Louisiana average.
Lead Exposure Risk for Children in Deville
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Although utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 35% of Deville stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.

Flood & Climate Risk in Deville
Deville's NFIP record reflects high flood exposure — 1182 claims spanning a long history of significant events, with 100% of ZIP codes in FEMA-designated zones. High flood frequency increases the probability of water quality disruptions at each point in the supply chain: treatment facilities, transmission infrastructure, and private wells all face elevated stress risk when flooding is a recurring feature rather than a rare exception.
Deville has a significant flood history with 1,182 FEMA flood insurance claims on record, averaging $11,479 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$1,200</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
